    Magnavox 142 chassis, smoking resistors, help!

    Given my fervor in discovering that 142 amps do indeed have treble when you replace bad HF filter capacitors, I got one unit running like a champ and the second is now making me fight to get it running correctly. I have attached a picture of the two misbehaving resistors (511), they like to...

    May have the opportunity to trade my up to spec pioneer sx-1010 for a dynaco pas3, st 70, and an fm-3 plus a little cash on my end I could really care less on the tuner. So that’s not a plus to me in anyway. But I have been very curious of tube separates lately. I’m running Cornwalls with the sx...

    Tube Amp: Warming Up & Idling

    Some simple questions: 1. Tube amp should not be powered on without speakers connected to it. True? 2. Some manufacturers suggest that their tube amps sound best after 30 minutes powered on. Should we play any music on it during that period of time, or should we just leave it silent while...

    Klipsch KG 5.5 vis-a-vis Zu Dirty Weekend

    Choosing between a KG 5.5 OR Zu DW to pair with my Scott 222. Thoughts on how they would differ? Anybody matched either speakers to a low watt tube amp? Very slim picking in my part of the world, so not too many choices for highly efficient speakers.

    I heard a guy say that he always runs hit Scott through a variac to keep it at 117v. Is there any real reason for this? I understand wall sockets can be 120-125v, just curious if that was enough to damage a amp that has be restored.
